ABSTRACT:
An explosion protection apparatus for installation in potentially explosive industrial installations for the purpose of automatically preventing a pressure wave and/or flame breaking through from a potentially explosive installation part to adjacent installation parts, has a sensor for explosion identification, which can be arranged in the potentially explosive installation part or can be connected to it. The sensor is electrically connected to an initiation device (1) which, in its basic state, holds a closing device (3) in its open position via an interlocking device (2) and with the aid of an active magnetic field of an electromagnet (5), and can be operated by sensor signals. The closing device (3) is prestressed such that, after operation of the initiation device (1), it is moved to its closed position. It can be arranged between the installation parts to be protected and the potentially explosive installation part.
